Railroad-chair



UNITED 'STATES PATENT OFFICE.

BRITTON M. EVANS, OF DOWNINGTOWN, PENNSYLVANIA.

RAILROAD-CHAIR.

Specification of Letters Patent No.

To all whom it may concern.'

Be it known that I, BRiTToN of Downingtown, in the county of Chester and State of Pennsylvania, have invented a new and Improved Railroad-Chair to Dispense With the Use of Wedges; and I do hereby declare that the following is a full and eXact description.

The nature of my invention is intended to obviate the necessity of wedging the wagon rail, and is expected by the invention to supersede the chair now in use.

To enable others skilled in the art of casting and laying railroads to make and use my invention, I will proceed to describe itsV M. EVANS,

1,442, dated December 27, 1889*.

A on the plan represents a movable jaw, which slides into the beveled shoulders B and C, and when moved to its place is confined by the pin D. After having placed the rail into the part of the chair E, the jaw A, is driven to its place, fastenedy by the pin D, firmly grasping the rail, and securing it in its proper position without the assistance of any wedge.

I would have it understood that I am aware that railroad chairs have been made with a movable jaw, and secured by means of wedges. I do not therefore claim that as my invention; but

What I doV claim as my invention, and desire to secure by Lette-rs Patent, is

Making the movable jaw with a dovetail, and to t into a corresponding slide in the chair, and secured by a pin, as above de-V scribed.

BRITTON M. EVANS.
